Question

我首先要为这个问题的长度道歉，但希望提供这些信息会有所帮助。

我试图在多个xml文档上使用单个xsl，它适用于我的原始文档（房间中四面墙的文本，每个墙表示为TEI surfaceGrp元素）。但是，现在我需要修改xsl来处理额外的TEI surfaceGrp元素，表示书面页面的两面，然后是页面集合。

我对四面墙的原始xml代码是这样的：

<TEI>
<sourceDoc>
    <surfaceGrp xml:id="wall" n="South Wall">
        <surface xml:id="EETS.T.29">
            <label>Verse 29</label>
            <graphic url="sw_test_1.jpg"/>
            <zone>
                <line/>
            </zone>
        </surface>
        <surface xml:id="EETS.T.30">
            <label>Verse 30</label>
            <graphic url="sw_test_2.jpg"/>
            <zone>
                <line/>
            </zone>
        </surface>
        <surface xml:id="EETS.T.27">
            <label>Verse 27</label>
            <graphic url="sw_test_3.jpg"/>
            <zone>
                <line/>
            </zone>
        </surface>
        <surface xml:id="EETS.T.56">

            <graphic url="sw_test_4.jpg"/>
            <zone>
                <line/>
            </zone>
        </surface>
        <surface xml:id="EETS.T.57">
            <label>Verse 57</label>
            <graphic url="sw_test_5.jpg"/>
            <zone>
                <line/>
            </zone>
        </surface>
        <surface xml:id="EETS.T.58">
            <label>Verse 58</label>
            <graphic url="sw_test_6.jpg"/>
            <zone>
                <line/>
            </zone>
        </surface>
        <surface xml:id="EETS.T.59">
            <label>Verse 59</label>
            <graphic url="sw_test_7.jpg"/>
            <zone>
                <line/>
            </zone>
        </surface>
    </surfaceGrp>
    <surfaceGrp xml:id="wall" n="West Wall">
        <surface xml:id="EETS.T.60">
            <label>Verse 60</label>
            <graphic url="ww_test_1.jpg"/>

                <line/>

        <surface xml:id="EETS.T.63">

            <zone>
                <line/>
            </zone>
        </surface>
    </surfaceGrp>
</sourceDoc>

我转换为以下html

<h1 class="menuHeader">
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_1-thumbnail.html">
        <img class="thumbnail" src="../../Testament/Clopton/Thumbnails/sw_test_1-thumbnail.jpg"

</span>

    <a class="nav_link" href="sw_test_2-thumbnail.html">
        <img class="thumbnail" src="../../Testament/Clopton/Thumbnails/sw_test_2-thumbnail.jpg"
            alt="Verse 30"/>
    </a>
</span>
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_3-thumbnail.html">
        <img class="thumbnail" src="../../Testament/Clopton/Thumbnails/sw_test_3-thumbnail.jpg"

</span>
<span class="menuitem" id="image_thumbnail">

            alt="Verse 56"/>
    </a>
</span>
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_5-thumbnail.html">
        <img class="thumbnail" src="../../Testament/Clopton/Thumbnails/sw_test_5-thumbnail.jpg"
            alt="Verse 57"/>
    </a>
</span>
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_6-thumbnail.html">
        <img class="thumbnail" src="../../Testament/Clopton/Thumbnails/sw_test_6-thumbnail.jpg"
            alt="Verse 58"/>
    </a>
</span>
<span class="menuitem" id="image_thumbnail">
    <a class="nav_link" href="sw_test_7-thumbnail.html">

</span>
<span class="menuitem" id="previousItem">
    <a class="nav_link" href="sw_test_6.html"> Previous</a>
</span>
<span class="menuitem" id="nextItem">
    <a class="nav_link" href="ww_test_1.html">Next</a>
</span>

通过这个xsl：

    <h1 class="menuHeader">

当我在带有额外surfaceGrp元素的新文档上运行它时，

我只获得一页的信息。这是有道理的，因为页面适合墙壁在原始代码中执行的相同surfaceGrp插槽。但是当我尝试修改代码以升级到页面集合

我得到了相同的结果。我不明白为什么。我显然不明白前兄弟和后兄弟以及我以为我做过，如果有更清洁的方法来实现我想要的东西，我会乐意使用它。

Answer 1

我不明白你想要实现什么，但你的一些代码看起来很奇怪，例如你想用

实现什么？

    <xsl:variable name="total_blocks">
        <xsl:value-of select="../last()"/>
    </xsl:variable>

？通常，此类构造可以写为<xsl:variable name="total_blocks" select="../last()"/>，但只要有父节点../last()，表达式1就会返回..。

另一个奇怪的是count(../following-sibling::node()/position())，我认为这不仅仅是count(../following-sibling::node())。

前级兄弟和后级兄弟不使用其他元素
